Problems solved by technology
Whether it is a gas-liquid system or a liquid-liquid system, dissolved oxygen is the key limiting factor of the oxidation reaction, and oxygen is a kind of insoluble gas. Under standard conditions, the equilibrium concentration of oxygen is 8.5g / m3, which is only glucose The solubility is 1 / 6000, and the lack of molecular oxygen leads to low oxidation reaction rate, low product quality, and limited dissolved oxygen in oxidation reaction. There are many shortcomings in the current reactor used in oxidation reaction system

The invention provides a super-gravity oxidation reactor device and application. The device comprises a super-gravity reactor body and a passive disturbance component, when a liquid hits against a collision part of the passive disturbance component after being thrown out of a rotary chamber, the collision part is rotated, a bottom passive disturbance part is driven to rotate, and liquid-liquid mass transfer of the reaction system is strengthened; in an upper cavity, the contact area of two fluids is increased through the super-gravity reactor body so as to strengthen mass transfer; in a lowercavity, mixing of the two fluids is improved through rotation, the time for reacting is prolonged, mass transfer and mixing are further strengthened, and meanwhile, efficient utilization of energy isachieved. Mechanical energy of a rotor is transformed into kinetic energy of the fluids, due to collision, the kinetic energy of the fluids are transformed into rotary mechanical energy of the collision part, the disturbance part is further rotated, and the problem that the fluids which rotate at a high speed hit against the reaction cavities to cause leakage of the reaction cavities is prevented.
Description
technical field [0001] The invention relates to the technical field of reactors, and more specifically, to a high gravity oxidation reactor device and its application. Background technique [0002] With the rise of modern biotechnology, the application of biochemical industry has involved many fields such as chemical raw materials, medicine, food, environmental protection, etc. Most of the biochemical reactions are oxidation reactions. Oxidation reaction is an important reaction process in the production of bulk chemicals and intermediates, such as the oxidation of ethylene to produce acetaldehyde, the use of hydrogen peroxide to oxidize TMP to produce TMQ, an intermediate for the production of vitamin E, etc. Whether it is a gas-liquid system or a liquid-liquid system, dissolved oxygen is the key limiting factor of the oxidation reaction, and oxygen is a kind of insoluble gas. Under standard conditions, the equilibrium concentration of oxygen is 8.5g / m3, which is only gluco...
